Handling guidance

Shipping, storage and sampling

How is the lipid shipped, and how should I store it?
Ships from Shanghai. Storage: 2 years -20°C Powder, 2 weeks 4°C in DMSO, 6 months -80°C in DMSO
Pure lipid or solution — which should I choose?
Pure lipid is generally more stable during shipping and storage, so we usually recommend the pure form. A solution in ethanol or chloroform can be supplied when required by your workflow. Tell us the intended application, solvent and target concentration so the most suitable format can be confirmed.
